cate, 1-2.5 em. long, straight or arcuate, delicately long-pilose; lamina (including the spread- 
ing fertile basal pinnae) ovate or deltoid-ovate, 1.5-2.5 cm. long, 1-1.8 cm. broad, obtuse, 
the upper half obliquely pinnatifid, the lower half pinnate; primary segments and pinnae 
3 or 4 pairs below the obliquely crenate-lobate apex, the basal (fertile) pinnae mostly a lit- 
tle shorter than the next, 5-10 mm. long, subbipinnate at the base, flattish, inequilateral, 
rhombic-ovate to narrowly deltoid, the divisions narrowly foliaceo-marginate, densely 
glandular-pilose; spores striate, smooth, the angles slightly produced; sterile pinnae and 
segments approximate or contiguous, the lowermost sessile, pinnatifid at the base, ob- 
liquely lobed or merely crenate, the lobes or crenations only 1 or 2 pairs, obtuse or rounded ; 
leaf-tissue delicately herbaceous, glandular and conspicuously whitish-pilose upon both sur- 
faces, glabrescent with age, then somewhat lustrous above. Sterile fronds similar but not 
exceeding 3 cm. in length; lamina deltoid, up to 1.5 cm. long, similar to the sterile por- 
tion of the fertile fronds. 
TYPE LOCALITY: Cerro Colorado, vicinity of Culiacan, Sinaloa, Mexico, in shallow soil on the 
face of perpendicular cliffs. 
DISTRIBUTION : Known only from the original specimens (Brandegee).

Rhizome creeping; stipes of the fertile fronds not equaling the sterile fronds. Fertile 
fronds long-stipitate, the stipe about as long as the lamina, brownish-stramineous, stoutish, 
sulcate along the ventral face, glabrescent, at the base somewhat rough from the persistent 
bases of the stiff yellowish-brown hairs; lamina (including the spreading fertile basal 
pinnae) deltoid to deltoid-ovate, up to 35 cm. long and 26 cm. broad, tripinnate; pinnae 
14-16 pairs, the fertile (basal) ones deltoid, 12-15 cm. long, up to 11.5 cm. broad at the base, 
with about 11 pairs of flat spreading deltoid-oblong pinnules, the lowermost basal ones of 
these about 6 cm. long and 2.2 cm. broad at the base, stalked (9 mm.), with about 9 pairs 
of flat deltoid-oblong mostly short-stalked segments, these bipinnatifid, minutely pilose ; 
spores broadly striate, scabro-verruculose, the angles produced; sterile pinnae spreading, 
contiguous, petiolate from a cordate base, unequally ovate-deltoid, acuminate, the larger 
ones with 10 or 11 pairs of pinnules, basiscopic, the inferior basal pinnules petiolate, 
deltoid-lanceolate from a cordate base, about 5 cm. long and 2.5 cm. broad at the base, 
with about 7 pairs of ovate to ovate-oblong acute segments, the basal ones trilobate, the 
margins a little thickened, obscurely denticulate-sinuate; upper pinnae narrower, oblong- 
lanceolate, finally adnate and confluent at the acuminate apex ; leaf-tissue herbaceous, dull 
dark-greenish above, a little paler below, minutely and scantily glandular upon both sur- 
faces, glabrous above, nearly so below; veins elevated on both surfaces, slender. Sterile 
fronds similar but smaller, the pinnae (from description) narrower, ovate-lanceolate ; 
pinnules of the lower pinnae (or at least of the lowermost) anadromous, of the upper ones 
catadromous. 
TYPE LOCALITY : Serra dos Orgaos au Morro Queimado, Chemin dos Macacos, Brazil. 
DISTRIBUTION : Costa Rica or Veragua, Panama ; also in Brazil.

Rhizomes slender or stoutish, horizontally creeping, sometimes rather widely so; 
fronds usually several, close, the stipe of the fertile fronds scarcely exceeding the sterile 
fronds. Fertile fronds 15-57 cm. long; stipes 5-40 cm. long, stoutish, dull- or yellowish- 
stramineous from a darker base, straight or subflexuous, deciduously pilose; sterile lamina 
ovate-deltoid, 5-15 cm. long and broad, acute, bipinnate, nearly tripinnate at the base, the 
rachis similar to the stipe, the secondary rachises densely clothed with long subpersistent 
ferruginous hairs; pinnae 6-11 pairs, mostly contiguous or overlapping, rarely apart, 
spreading, the lower and middle ones petiolate, ovate to oblong-lanceolate from a subcor- 
date base, subacute, the lowermost with 6-10 pairs of distant pinnules, the basal of these
